TAKE-UP MECHANISM FOR SLAT-AND-WIRE FABRIC LOOMS.

SPECIFICATION forming part of Letters Patent No.541,563, dated June 25, 1895.

Application filed November 30, 1894. Serial No. 530,355- (No model.)

To all whom it may concern:

Be it known that I, LOBEGOTT MoLLARr, a citizen of the United States, and a resident of Watertown, in the county 'of Jefferson and State of Wisconsin, have invented certain new and useful Improvements in Slat-and-Wire Fabric Looms; and Ipdo'hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its objectto improve the makeup mechanism of slat-and-wire fabric looms such as is set forth in Patent N 0. 517,058, dated March 27, 1894; and it consists in certain peculiarities ofconstruction and combination of parts hereinafter specified with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a plan view of my improved take-up mechanism ap: plied to a slat-and-wire fabric loom of that description set forth in the aforesaid patent. Fig. 2 is an elevation of the same with certain of the parts in section. Fig. 3 is a detail plan view of said mechanism partly broken away andin section; and Figs. 4 and 5 are sectional views, respectively, taken on lines at tand 5 5 of Fig. 3.

Referring by letter to the drawings, A represents a vertical stud held by a set-screw 1) against rotation in the 1oombase B, and loose on this stud is the hub of a circular disk 0 having a depending flange c, the disk being provided with notched ribs (1 for the engagement of a pin or the ends of lugs 5 extending laterally from a longitudinal slotted roller D that is stepped on said disk to turn therewith, this connection of the'roller and disk being substantially the same as shown and described in the patent above noted.

Loose on the disk-hub is the hub f of a lever E that opposes the edge of the disk-flange at two points in opposite directions from said hub. The rear end of the'lever is provided with an eye g for the engagement of a boss h extending from a sleeve F on a link-rod G, the latter being in loose connection with the lower end of the reciprooative rod H to which the beater-arms I of the loom are attached.

Like in the above named patent, the fabric J produced by the loom is run over a supporting roller K and wound on the roller D herein specified. It is also to be understood that the slat and fabric guides L, the crosshead M engaged by the rod H, the guide N for the cross-head, and the drive-mechanism herein shown are similar to like parts in said patent.

A nut it run on the forward end of the linkrod G prevents the latter from pulling through the sleeve F when the beater-rod H is on its rear travel, and said link-rod is herein shown as surrounded by two spiral-springs P, Q, of a difierent power arranged in successive order these springs being intermediate of a collarj and said sleeve. In order to vary the springtension, the collar j is adjustable on the linkrod G and a pin 11111 through any one of a series of perforations in the rod serves to hold said collar in adjusted position. Whilel obtain a better tensionby employing two springs of different power, it is practical to utilize a single spring as part of the improved take-up mechanism herein set forth.

The loom-base herein shown is provided with vertical bosses m having lengthwise grooves" engaged by rounded inner ends of a pair of dogs R having friction blocks n in their outer ends faced against the inside of the flange c that depends from the disk 0 above specified. The bosses are eccentric to the stud Aabove specified anda spring p connects each boss and the dog engaged therewith. The hub f of the lever E is also provided with lengthwise grooves, eccentric to the stud A, and these ends of a pair of dogs S having friction blocks 0" in their outer ends facing the inside-of the disk-flange c, springs 3 being em'ployed'to connect the latter dogs and lever-hub.

The dogs in pivotal connection with the lever are intermediate of those in'like connection with theloom-base and the springs in connection with the several dogsa'ct by contraction to keep said dogs in contact with the opposing disk-flange and compensate for wear. Each pair of dogs operate to clutch the disk and that pair of said dogs on the loom base hold the disk against rotation except at such times as the lever E is on its forward throw. While I have shown the bosses m on the loombase as will be the practice in constructing and separated from each other by awasher i,

latter grooves are engaged by rounded inner new looms, they may be on a separate plate secured by any suitable means on the base of a loorn as now built according to the patent herein noted.

In practice when the reciprocative beaterrod H is' on its forward travel the link-rod G and springs thereon are moved in the same di rection. Consequently if these springs are of sufficient tension the lever E is thrown forward to effect a clutch-action of the dogs S on the adjacent flange of diskO and therebyim part rotary motion to said disk and fabricroller in lock therewith. On the reverse movement of the beater-rod and lever the dogs R clutch the adjacent flan ge while the otherdogs S slip loose thereon, whereby the disk and fabric-roller are held stationary, Hence it will be seen that there is an intermittent rotation of said disk and fabric roller coincident with the forward travel of said beater rod to take up slack in the fabric.

As the fabric accumulates on the roller D the spring-tension is proportionately increased from time to time by adjusting the collar j on the link-rod whereby I insure the intermittent rotation of the disk to which said roll is coupled. It is also to be noticed that as the fabric-roll grows larger less throw of thelever E is necessary and hence when there has been sufficient movement of said roll to take up the slack the link-rod G is free to move in the sleeve F while the beater-rod H is completing its forward throw.

By suitable adjustment of the spring--tension herein set forth the fabric may be woven close or otherwise at will, the tension being greatest for open woven fabric.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
